This is a picture of my PC Chips Bki 810 Book PC.

It's only a small computer, measuring only about 12" long by 11" wide and a little over 3" thick.

Mine has a 400Mhz Celeron CPU, and it had 127 Mb of RAM to which I added another 256 MB card, so it has 383 MB of memory now.

UPDATE: It has since been upgraded to 512 MB of RAM.

In spite of its small  size and moderate specs, it's a very well designed little PC, and  it performs very well, better than many larger PCs.

And here's a picture of the miniature 100W power supply unit that  fits inside the small  case of the Book PC.

It's only 3" x 4" x 2 1/2"

My PC 1oo Power Supply Unit has become faulty and they don't make them anymore. I can't buy a new one anywhere.

Perhaps I could repair the old one myself, but I don't have the tools or the right training, and technicians I've tried haven't been keen on doing any work on it for me.

This is a picture of the Book PC with the PC 100 Power supply removed.

All the other parts of the computer are fine. It's a waste to have to throw away a good computer just because one part of it is no good anymore.

Of course it won't fit inside my Book Pc's tiny case, so instead I put the Book PC and the new power supply into an old ATX case I had kicking around.

Here's the same picture again, but smaller so you can see the whole thing at once.

All I had to do was screw the Book PC's whole motherboard tray to the existing motherboard tray of the ATX case.

i used screw holes that were already there, no drilling was necessary.

See how neat it fits in there?

The large fan under the 550 Watt PSU will certainly be more than enough to keep everything nice and cool.

 This photo shows how nicely the back panel of the Book PC lines up with the hole in the back of the ATX computer case.

It looks quite professional eh? 

All the ports are exposed, no cutting was necessary. I will have no problem  plugging everything in.

Well, to be honest, there is one port covered up, but that was only the dialup modem port, which I never use anyway.

The 550 Watt ATX power supply unit came with a 24 pin molex minifit junior type of connector which is standard for ATX power supplies of this output rating.

Needless to say, it won't just plug directly in to the little Book PC's motherboard, which has only a six pin socket.

As you can see, I have removed six of the wires from this plug. See the empty holes?

The metal terminals were held inside the plastic plug by little lock tabs, something like the barbs of a spear or arrow head. I simply pressed those in with a very thin srewdriver while I wiggled and pulled on each wires until I was able to remove the wires that I needed.

 This is the view from the 24 pin molex mini fit junior PC power supply plug from the front.

The pins are numbered from one to twelve down the left-hand side and then from thirteen to twenty-four down the right hand side of the plug when the lock tab is to the right, and the plug is facing us, as shown in this picture.

Pin out for the 24 pin ATX connector was:

The ones we need to remove for the Book PC are any two black wires, the two yellow wires and the purple one and the green one. 

The ones show in yellow are the ones I used, but as long as you get the right colors you can use different black ones if you want. There are lots of black wires, but you won't have a choice for the other colors because there are only two yellows and one green and one purple wire available.

 This photo shows the six pin power plug for the Bki 810 motherboard of the PC Chips Book PC from the back  and upside down but with a green, a purple wire, two black wires and two yellow wires inserted into it in the right holes.

 Here's the right way to look at the six pin plug for the Bki 810 Book PC's motherboard. Once again, the clip is to the right in this picture, with the plug facing us.

Pins one to three are numbered down the left, and numbers four, five and six are to the right in this picture.

                                                               pin1  +5VSB (purple)          pin4  PS_ON# (green)
                                                               pin2  GND     (black)           pin5  +12V      (yellow) (lock tab)
                                                               pin3  GND     (black)           pin6  +12V      (yellow)

Just make sure you get the right wires in the right holes if you decide to try the same thing as I did.

 And here's a photo of the way it looks when it's plugged in, the front of the Book PC is to the right and the back panel of the Book PC is to the left in this picture.

You can see a bit of one of the RAM cards showing at the top of this photo.

Here, the Book PC, disguised as an ATX computer, (in the beige case to the left of this photo), joins the other computers in my computer room.

Even with only a 400 Mhz Celeron CPU and 383 Mb of RAM, it runs Ubuntu Hardy Heron very well thank you. 

Ubuntu is a replacement for Windows and actually it is quite a lot better than Windows XP or Vista.

 UPDATE: This little computer is still working fine on the 27th March 2010 and I am looking forward to installing Ubuntu Lucid Lynx in it along with Windows 98 when Ubuntu Lucid Lynx is released.
